North Northamptonshire Council is the local planning authority. It is a unitary council, so planning, building control and the roads all sit with the same authority, which keeps the practical side simpler than in a two-tier district.
Most of the town is undesignated
Because so much of Burton Latimer is modern estate housing, the majority of properties here are neither listed nor in a conservation area, and it is worth saying that plainly rather than implying constraints that do not apply. On that stock a single storey rear extension of up to four metres on a detached house or three on a semi frequently falls within permitted development, there is usually side access, and a skip stands on the drive.
The larger home extension route is also available on unlisted property, allowing up to eight metres on a detached house or six on any other by prior approval rather than full permission, with neighbours notified and an answer in about six weeks.
The older core
Around the historic centre and the church the picture is different, with older buildings, tighter plots and designations that need checking before anything is drawn. The same applies in the surrounding villages.
What the council will want to see
Where a site has a history of quarrying or industrial use, ground conditions can become a matter for the application rather than only for the builder. That is normal and manageable, and it is far better established at the outset than raised late.
Permitted development is not an exemption from Building Regulations, and a full plans application is still required. We do not make that application, but we arrange and meet the inspections that follow it and we see the work through to sign off.
